Knowing the difference between a weed in the backyard and the weed used to intoxicate is becoming increasingly rare (Nature Deficit Disorder Takes Root) as children of the post-millennial years are becoming more disconnected with nature. Nature Deficit Disorder, NDD, was termed in 2005 by researcher and author, Robert Louv in his book, Last Child in the Woods. It is used to describe the nature void people have in their life. NDD isn’t an official medical term but there are significant effects it…
This write-up focusses on three concepts of sound assessment practice namely reliability, feasibility and educational impact. Reliability Reliability refers to the ‘reproducibility’, ‘repeatability’ or ‘consistency’ of the scores obtained from an assessment (Memon et al, 2010; van der Vleuten et al, 2005). Reliability is generally expressed as a coefficient ranging from 0 (no reliability) to 1 (perfect reliability). Since it is difficult to achieve perfect reliability in any assessment, a…
The alternative hypothesis is the existing hypothesis that has already been proven or maintained as the true outcome. For instance, water is wet. This is the alternative hypothesis, which is also known as the maintained hypothesis. If a researcher would like to explore different possibilities, a new study will be conducted with a new hypothesis which would be quickly disproven. Of course water is wet, and any other hypothesis would be the null…
the p-value “defines the smallest value of alpha for which the null hypothesis can be rejected” (p. 312). When we carry out a statistics test, we are testing the hypothesis that the groups are the same (the null hypothesis). If it is determined that there is a p value of 0.05 or lower, than the null hypothesis is rejected and the alternate hypothesis is accepted. Likewise, if the p value is higher than 0.05, the null hypothesis should be accepted and the two groups should be measured to be the…
80 degrees Celsius, the catechol will be at its optimal absorbance. The alternate hypothesis tested for this following experiment was that there is a significant relationship between catechol and pH. In contrast, the null hypothesis states that there is no significant relationship between catechol and oxidase and pH. This hypothesis will be supported if the rate of catechol oxidase does not increase. The hypothesis was tested by observing the reaction time of catechol oxidase at four different…
1.20 RESEARCH GAP There are number of studies about employee attrition and retention in various industries belongs to different sectors. Researchers have mainly given importance to study and investigate the employee attrition and retention in IT companies situated in IT hubs and in Tier I cities. These cities are significantly differed in socioeconomic and cultural aspects comparing Tier II cities. The studies on employee attrition and retention in IT companies situated in Tier II cities are…
UFO’s - unidentified flying objects - and aliens are topics every American knows. At the start of the Cold War came the first sighting of UFO's. This began a new interesting phenomenon. The US government began investigating reports of UFO sightings for the slight possible chance that it really could be extraterrestrials. Not long after the CIA began their study on UFO’s a rancher reported a crashed disc on his land. There those who believe in the existence of aliens and that the government is…
neutral because scientists have that desire to want something that will describe the natural world. Scientist first come up with a hypothesis, which is supposed to be objective but since labs are carried out to find a particular thing, the hypothesis can not be objective. Scientist use intuition from observations or other events to develop a hypothesis and in doing so they are carrying bias in their hypothesis. An example of subjectivity in the natural sciences are when scientists want to find…
INTRODUCTION: Many processes in the world can be studied and analyzed; everything is a process in one way or another. One system that might not be considered a “process” at first glance, but which operates as one, is the education system. If you consider graduation rates, literacy rates, and the general intelligence of an educated populace as the variables being tested, one could determine if the education system is in control or reliable. We originally wanted to perform this study to compare…

Retrieved January 31, 2017. The basic concept that is being explored are about enzymes. Enzymes are proteins that are known for being sparkplugs in a chemical reaction. Enzymes have a shape and for them to ‘spark’ they must have the proper substrate for it to work U. This does not change the enzyme’s…
